Abstract
The invention provides an ardealite harmless treating agent. The treating agent is characterized in that the ardealite treating agent is lime, and the application weight proportion of the lime to the ardealite is (0.5-1.5):100. The invention has the advantages that: the ardealite is converted into a conventional solid waste, the requirement on constructing a storage yard of the waste is greatly reduced, and the investment on storage yard construction can be reduced by ** Yuan per year. Meanwhile, the ardealite which is treated by lime can be instantly used for producing an agricultural trace element fertilizer and producing a gypsum board, and can be used as a cement admixture or for pit filling and paving.
Description
Technical field
The present invention relates to chemical industry waste disposal field.
Background technology
Ardealite is the solid waste in the production process of phosphoric acid, owing to wherein contain poisonous polluters such as fluorine, arsenic, lead, copper, chromium and phosphorus, it is stored up for a long time and can form pollution to the surface water around the stockyard, underground water and soil, ardealite exceeds standard because of the fluoride in its leachate and phosphorus, has leaching toxicity, country classifies it as hazardous waste, and its stockyard construction cost is very expensive.Overwhelming majority enterprise no fund is built the stockyard by national relevant requirements, and the underground water formation of locality is polluted, and has had a strong impact on human livestock drinking water around the stockyard.
Summary of the invention
Purpose of the present invention just provides a kind of ardealite innocent inorganic agent, and the ardealite innocent inorganic agent is a lime, uses weight proportion to be: lime: ardealite=0.5-1: 100.
Advantage of the present invention is that it can be converted into ardealite general solid waste, and its stockyard requirements on Construction reduces greatly, can reduce 34.7 hundred million yuan of stockyard construction investments every year.Simultaneously, the ardealite after lime treatment can be used for producing agricultural trace-element fertilizer immediately, produces plasterboard and is used as cement admixture, also can be used for filling out the hole and builds the road
The specific embodiment:
The 80kg pulverized limestone is added 10000kg to be treated to stir evenly in the ardealite of harmless treatment and gets final product.The every index of its leachate of ardealite after above-mentioned processing does not all exceed standard.
